简要总结
This was a Phase 2 prospective, randomized, crossover study of Flurpiridaz (18F) Injection for PET-MPI in participants referred for evaluation of known coronary artery disease (CAD) or for suspected CAD with intermediate to high pre-test probability (PTP). The objective is to assess the difference and variability between 2 sets of rest images synthesized by the same or 2 different manufacturing processes. Twenty-eight evaluable [participants were enrolled in this study and underwent 2 Flurpiridaz (18F) Injection PET-MPI at rest. Each participant attended a Screening Visit at least 2 days and up to 14 days prior to the first Flurpiridaz (18F) Injection PET-MPI. The participants were randomized 1:1:1:1 to 4 possible sequences of receiving 2 doses of Flurpiridaz (18F) Injection: 2 groups of 7 participants received 2 Flurpiridaz (18F) Injection doses synthesized by the same manufacturing processes (either HPLC or SPE) and 2 groups of 7 subjects will receive 2 Flurpiridaz (18F) Injection doses synthesized by different manufacturing processes (1 dose by HPLC followed by 1 dose by SPE or 1 dose by SPE followed by 1 dose by HPLC). All participants were followed up by telephone for adverse events (AEs) and serious AEs (SAEs) at 24 (+8) hours following each Flurpiridaz (18F) Injection administration.

入选标准
- •* The participant was a man or woman ≥18 years of age
- •The participant was undergoing evaluation of known CAD or for suspected CAD with an intermediate to high PTP.
- •The participant had read, signed, and dated an informed consent form (ICF) prior to any study procedures being performed, and was willing to allow the study investigator to make the participant's medical records available to GE Healthcare.
- •The participant was male or was a nonpregnant, nonlactating female who was either surgically sterile (had a documented bilateral tubal ligation and oophorectomy and/or documented hysterectomy [bilateral tubal ligation alone was insufficient]) or was post-menopausal (cessation of menses for more than 1 year); enrollment in the study without a pregnancy test at Screening was allowed for these categories of female participants. For women of childbearing potential, the results of either a urine or serum human chorionic gonadotropin pregnancy test (with the result known on the day of each radiopharmaceutical administration) must be negative. These participants must have been practicing appropriate birth control from the time of the screening to 30 days after the second radiopharmaceutical administration. Such methods included: hormonal contraception including oral contraceptives; intrauterine device; intrauterine hormone releasing system; bilateral tubal occlusion; vasectomized partner; sexual abstinence; adequate barrier method with spermicide (e.g., diaphragm, condom).
- •The participant was able and willing to comply with all study procedures as described in the protocol.
排除标准
- •* Participants who were pregnant, may possibly be pregnant, or wish (including their partners) to become pregnant during the study period, or were lactating

- •Participants enrolled in another clinical study within the 30 days before enrollment in this study.
- •Participants previously enrolled in this study or any Flurpiridaz (18F) Injection study.

结局指标
主要结局
Intra-reader Difference of Summed Rest Score (SRS) for Positron Emission Tomography (PET) Myocardial Perfusion Imaging (MPI)
时间窗: Up to 2 weeks
3 qualified readers (independent from the study) performed independent reads of all MPI images, inclusive of standard 17-segment polar-maps of perfusion defects. Each reader scored the perfusion pattern in each segment (17 segments) using a 5-point scale score range from 0 to 4: Normal 0, Minimal, mild impairment of perfusion = 1, Moderate impairment of perfusion = 2, Significant impairment of perfusion = 3, No perfusion = 4. Higher score indicated = impairment of perfusion. SRS was calculated by summing individual scores from each of 17 segments to give an overall score between 0 and 68; a score of 0 indicates normal outcome and scores more than 0 indicate increasingly worse outcomes as the score increases. The summed score of the 17 segments SRS was used for analysis. Intra-reader difference of SRS for PET MPI was reported.

Summed score of the 17 segments SRS was used for analysis. SR% is calculated by dividing the SRS by a number corresponding to the SRS value indicating a deficit of 4 in every segment and then multiplying the result by 100.
